On January 20, 2025, DeepSeek launched its landmark model, DeepSeek-R1, which quickly propelled the company to the top of the U.S. iOS Apple Store as the most downloaded free app. This release also triggered a notable downturn in U.S. financial stock markets. Nvidia(NVDA) drops nearly 17% as China’s cheaper AI model DeepSeek sparks global tech sell-off
Artificial intelligence continues to evolve at a breathtaking rate, with new breakthroughs appearing almost daily. For a long time, ChatGPT has maintained its leadership in AI-driven conversation, known for its expansive knowledge base and remarkably human-like interactions. Yet, DeepSeek’s introduction of the DeepSeek-R1 model has shaken the industry, posing a serious challenge to ChatGPT’s longstanding dominance.
What is Deepseek?
​DeepSeek is a Chinese artificial intelligence startup founded in 2023 by Liang Wenfeng, co-founder of the hedge fund High-Flyer Capital. Headquartered in Hangzhou, the company specializes in developing open-source large language models (LLMs) that are both cost-effective and highly efficient.​
In January 2025, DeepSeek released its flagship model, DeepSeek-R1, which was trained for approximately $6 million using Nvidia H800 chips—significantly less than the over $100 million reportedly spent on training models like OpenAI’s GPT-4. Despite its lower training costs, DeepSeek-R1 ** achieved performance levels comparable to leading AI models**, particularly in tasks requiring mathematical reasoning and problem-solving.
DeepSeek AI’s open-source approach, releasing its models under the permissive MIT License, has garnered attention for promoting transparency and collaboration in AI development. The company’s success has been viewed as a significant moment in the global AI landscape, challenging the dominance of U.S.-based AI firms and highlighting China’s growing capabilities in the field.​
Summary of ChatGPT
ChatGPT is a conversational AI developed by OpenAI, launched in November 2022, designed to understand and generate human-like text based on user prompts. Built on advanced large language models like GPT-4 and GPT-4o, ChatGPT has become a leading platform for tasks ranging from casual conversation to complex problem-solving, coding, writing, and professional support. Its strength lies in its vast knowledge base, natural interaction style, and ability to adapt to a wide range of topics. Since its launch, ChatGPT has helped popularize AI in everyday life, setting the standard for AI-driven communication.
Over the past two years, ChatGPT has undergone multiple updates. It allows users to select different GPT models, with the latest being GPT-4o. Additionally, it supports features such as web search, reasoning, and the inclusion of additional documents/images.
DeepSeek vs. ChatGPT: Feature Comparison
Model Architecture
| Feature | DeepSeek R1 | ChatGPT 4 |
|---|---|---|
| Model Architecture | Mixture of Experts (MoE) with 671B total parameters, activating only 37B per query | Dense model with 1.8T parameters used in every task |
| Training Strategy | Reinforcement Learning (RL) post-training, minimal supervised data use | Proprietary training with extensive human-labeled datasets |
| Reasoning Ability | Strong chain-of-thought reasoning, tailored for advanced problem-solving | Advanced multi-step reasoning, especially in STEM domains |
| Cost & Efficiency | Trained in 55 days on 2,048 Nvidia H800 GPUs, costing ~$5.5M | Estimated training cost exceeds $100M |
| Optimization Focus | High performance with efficient resource usage | Optimized for versatility across many tasks |
Performance Testing
DeepSeek-R1 demonstrates strong performance, particularly in tasks requiring advanced reasoning and problem-solving. Its Mixture-of-Experts architecture enables it to activate only a small subset of parameters for each task, making it highly efficient compared to traditional dense models. Trained at a fraction of the cost of competitors, DeepSeek-R1 is optimized for technical fields like mathematics, coding, and structured analysis.
In comparison, ChatGPT-4o excels in versatility and natural language capabilities. It delivers more nuanced, creative, and contextually rich responses across a broader range of topics. Although ChatGPT-4o requires significantly higher computational resources and cost to train, it remains the leader in general-purpose AI interactions.
Overall, DeepSeek-R1 stands out for efficiency, cost-effectiveness, and technical accuracy, while ChatGPT-4o maintains an edge in conversational quality, adaptability, and creativity.
